SHEET-METAL CAN.

Specification of Letters Patent.

Patented July 7, 1908.

To all whom it may concern: I

Be it known that I, MATTHEW MICHAEL KANE, a citizen of the United States of America, and resident of Rome, county of Floyd, State of Georgia, have invented certain new and useful Improvements in Sheet- Metal Cans, of which the following is a full the cap detached; and Figs. 3 and 4 are vertical sectional views taken at right angles to each other, showing the cap secured in place over the opening in the cover.

This invention has relation to that class of can closures in which the closing plate or cap is soldered in place over an opening in the cover and is adapted to be removed therefrom to 0 en the can by being coiled upon a key whic is adapted to be engaged in one end of the cap or plate and to be rotated across the opening thus winding the cap or plate upon the key.

The object of this invention is to so con struct the closure device that it may be read' ily and accurately placed over the o ening and be held accurately while beingso dered, While at the same time its easy removal shall not be interfered with; and a further object is to prevent the fastening solder from reaching the hole in the cover and falling into the interior of the can, as more fully hereinafter set forth.

In the top of the cover a is formed a suitable pouring hole I) and extending half-way around this opening is a groove 0 formed byangularly de ressing the metal of the cover. The two encs of this groove extend away from the opening tangentially to form extensions c, the depth of these extensions being the same as they main semi-circular groove 0 where they connect therewith and from that point gradually growing shallower until at their extreme outer ends they merge intothe upper face of the cover.

The closure plate d consists of a piece of sheet metal rovided at one end with a curved depending anged adapted to fit within the curved portion 0 of the groove and having ta ered portions (1 ada ted to lie and fit within the tapered extensions 0 of the groove.

The under face of this closure plate lies flat against the upper face of the cover around the opening I), and its lateral extension or tail-piece (1 also lies flat against the face of the cover and extends a short distance be yond the ends of the extensions 0 of the groove. This plate is affixed to the can by soldering around its curved edge at c, the solder being placed in the groove 0 and its extensions, there-being ample room for the solder between the depending flange of the late and the outer wall of the groove. A ittle solder is also placed between the tailpiece and the upper surface of the can, as shown at f in Fig. 4, thus making the closure device air-tight but at the same time leaving the extreme end of the tail piece free to be turned up for engagement wlth the opening key or with any other opening tool that may be employed as shown in Fig. 1.

It will be observed that the peculiar groove around the pouring opening preventssolder gaining access to the opening in closing the can and also accurately guides and centers and holds the cap while it is being fixed in position. At the same time, by extending the 'ends of the groove tangentially to the open ing and gradually decreasing their, de th to permit the tail-piece to lie flat upon t e up per face of the cover the ready removal of the cap plate is not interfered with. After the closure plate is removed a hole may be punctured in the cover at a suitable point opposite the pouring opening, and by means of the pointed end of the opening key, to permit ingress of air during the pouring action.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent, is-

1. A can having a pouring opening formed in its cover and a depression or groove partially around said opening, the ends of this groove extending away from the openin in an approximately tangential line, these lateral extensions decreasing in depth toward their ends, and a closure plate having a lateral tail piece, and a depending marginal flange adapted to fit in said groove and its extensions, the plate being fastened in place by a line of solder placed in said groove.

2. A can having an opening formed in its cover and a groove partially around said 0 enin at a dlstance from the edge thereof, t e ends of this groove extending away from the opening in approximately tangential lines, and a fiat closure plate having a tailpiece, and a dependingmarginal flange adapted to fit in sald groove and its extensions, this plate lyin directly upon that portion of the upper sur ace of the cover between the opening and the groove and being fastened in place by solder placed in said groove and un er the tail-piece.

In testimony whereof I hereunto aflix my tWo Witnesses 10 MATTHEWV MICHAEL KANE.
